Are Docker daemon going to be available on kubernetes 1.20 at gke

I have a cluster on GKE currently on version v1.19.9-gke.1400. Accordingly do kubernetes release notes, on 1.20 dockershim will be deprecated. My cluster is configured to auto-upgrades and in one specific application I use docker socket mapped to the application, where I run direct containers through their API.

My question: In a hypothetical upgrade of the cluster to the 1.20 version of kubernetes, the docker socket will be unavailable immediately? Or the deprecated flag only points that in the future it will be removed?
